Can you explain why my late mother always used tea to water her geraniums. She also infused banana skins for her roses and used the water from boiled eggs to water foliage plants Does this work, I wonder why?

Tea is made of leaves and the juice of leaves has a certain amount of nitrogen and other nutrients. It tends to make leafy gorwth however and it not ideal for geraniums, which do better with high potash feeds.
Banana skins have some potash and boiled-eggs water also has some nitrogen but tiny amoounts. But no ham in recycling the water rather than waste it. All of these ‘feeds’ would have a small beneficial effect, the tea being the most powerful of them.
